Die Letzten Tage Der Nacht by Graham Moore

Set in late-19th-century America, the novel follows a brilliant, idealistic young lawyer recruited to help a rival electrical pioneer in a high-stakes courtroom battle over the future of electric power; as patent wars, scientific spectacle, and personal ambition collide, he becomes entangled with inventors whose competing visions for powering cities—and the ruthless tactics used to protect those visions—force him to confront ethical compromises, shifting alliances, and the profound consequences of who controls technology.
